It was around 8 on a saturday night so I understand that they were busy, but our service wasn't that good. First they were out of stock on several bottles of wine, we had to order 3 bottles of wine before they actually had one we wanted. some of us ordered salads and half of us didn't get them until we reminded the waitress. The sushi was ok, definitely not the best i ever had. I am all about trendy and young places but the atmosphere was a little much, I felt like Nikko was trying too hard to be hip. It was a bit too much of a nightclub atmosphere for a place to have dinner, they had a dj spinning while we were there and it was so loud that the only person you could talk to was the person next to you, and there was also a girl passed out in the women's bathroom with the door locked.
Good things:
We had reservations and we were seated immediately and the cost was very reasonable. I paid around $45 (tip included) for a salad, sushi, and a half bottle of wine.
